1. A winding apparatus for winding a paper web, comprising:

  • a rotatably mounted reel spool onto which the paper web is wound to form a roll of paper;

    a support member forming a nip with the roll of paper;

    an actuator configured to control the distance between the support member and the roll of paper; and

    a measuring and controlling equipment comprising;

    a light-emitting member arranged to illuminate the roll of paper by light providing a line on the cylindrical surface of the roll of paper;

    a receptive system arranged to depict the line; and

    a control unit connected to the receptive system and arranged to analyze the depicted line in order to calculate the distance between the roll of paper and the support member and send a position-correcting signal to said actuator when the distance calculated deviates from a predetermined distance.
